PROCESS OF AND APPARATUS FOR AERATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 485,665, dated November 8, 1892;

Application filed February 13, 1892. Serial No. 421,391. (No model.)

T at whom it may concern:

Be it known that I, CARL H. SCHULTZ, a resi- .dent of the city, county, and State of New York, have invented an Improved Device for and Process of Aerating Liquids, of which the following is a specification, reference being had to the accompanying drawings, forming part hereof, wherein- Figure l is a side view, partly in section,

of my improved device for aerating liquids.

Fig. 2 is a detail bottom view, on an enlarged scale, of the compression-cup, which constitutes the main feature of my invention; and Fig. 3 is a vertical central section of the same on the line 3 3, Fig. 2.

This invention relates to a new methodand mechanism for intimately mixing'air or gases with liquids in vessels that are to contain the aerated liquids under pressure. The invenzo tion relates, mainly, to the class of liquids to which sod a-water belongs. Heretofore it was deemed necessary in order to obtain the requisite admixture of air or gas and liquid to agitate the liquid in the fountains or vessels which contained them, the mechanism for agitation being expensive, liable to get out of order, and for other reasons quite objectionable. It has been my endeavor to seek for means for producing the most intimate admixture of air or gas and liquid without the necessity of any agitating contrivance or its equivalent. I have succeeded in accomplishing the desired result by a very simple contrivance, which, briefly stated, is a compression-cup placed over the end of the pipe that leads the narrow slits at about right angles to the bore of said cup, through which said narrow slitsthe mixed gas and liquid are forced to enter the vessel after having been intimately admixed the one with the other in the pipe beneath the compression-cup.

In the drawings the letter A represents the vessel" to be charged with the aerated liquid. The letter 13 represents a suitable pump for forcing gas and liquid (we will say water) into It is not deemed necessary here to specify mechanism The contrivance, as shown, with the exception of the compression-cup hereinafter described, is entirely old and well known, and I will repeat that in the mechanism, as shown (excepting the compression-cup) and as heretofore used, it was essential and absolutely necessary that the vessel A contain an agitator of some kind in order to produce the aeration of the liquid'to the proper degree. I attach to the end of the pipe 0, within the lower part of the vessel A and below its water-line, a cup-like structure D, which I call the compression-cup. This compressioncup has an inner bore a in alignment with the bore of the tube 0; but above the upper end of this bore a is placed a cap 17, which is a solid plate having, by preference, a diameter greater than the lower portion of the cup, as shown in Fig. 3. Between the lower surface of the plate I) and the upper surface of that portion of the cup which comprises the tubular bore care three (more or less) very short studs d, which connect the two parts of the cup last above mentioned, and between which studs are exceedingly narrow slits e. In other words, the compression-cup D consists of a lower portion having a bore a, of an upper cap I), which is placed over the outlet of the bore a, and of narrow passages 6, extending at about right angles to the bore a beneath the cap b.

I have found that when the vessel A is first charged with gas and water and'the pump then forces gas and water through the pipe 0, said pipe carrying the compression-cup D, the contents of the tube or pipe 0 are abruptly arrested in their passage through the pipe by the cap I) and, so. to speak, constipated and forced to enter beneath the waterline of the vessel A through the slits or apertures e, and that by this abrupt change of di- "rection the pressure within the vessel and by will retain their admixed condition within the vessel A and that further agitation of the'contents of the vessel when charged is no longer necessary.

Having now described my invention, What I claim is 1. The compression -cup D, having lower bore (2, upper cap 1), placed over the end of the bore a, and narrow out1et-passage e below the cap I) and at about right angles with the bore a, substantially as and for the purpose herein shown and described.

2. In an apparatus for aerating liquids, the combination of the pump B and its gas and water discharge pipe 0 with the compressioncup D, placed on the discharge end of the pipe C, said compression-cup havingnarrow lateral outlets e beneath a solid cap b, all as and for the purpose herein shown and described. 3. The process herein described of aerating liquids, which process consists in forcing air and liquid from separate receptacles through a single conduit into a receiver and in constipating said air and liquid within said receiver and simultaneously changing the direction of their flow below the water-line of and within said receiver, so that said constipation, change of direction, and pressure within the receiver will cause the aeration of the liquid, as specified.
